To all whom it may concern:

Be it known that l, JosnPH E... CQQKBMQ a citizen of the UnitedStd'll855f681d111g at Elkharty in the county of Elkhart @tate ofIndiana, have invented certain new and useful Improvements inVil'eighing-Scales of which the following is a specification.

This invention relates tov improvements in weighing scales and moreparticularly to that type known as platform scales and in which isemployed a horizontally disposed conical dial, and the primary object ofthe invention is to construct an improved co npact scale of thischaracter in which the platform will be close to the dial. I

A in her object, 's to construct an improvedscale of this character inwhich the dial will be arranged in close proximity to the platform andin such a. position with relation thereto that the dial. will notinterfere with the objects to be weighed and the objects will notobstruct the dial and at th same time produce a compact scale requiringbut a comparatively small space on tie counter or support.

A further object is to provide an improved scale of this character inwhich the parts are so arranged thatthe user will be close to the dial.I

A. further object is to censtruct, an improved scale of thiscbaracter inwhich the platform will be supported at a low elevation and at the sametime provide an improved scale having a large capacity.

To the attainment of these ends and the accomplishment of other new anduseful objects, as willappear, the invention consists in the featuresof-novelty in the construction, combination and arrangement oi theseveral parts l ereinafte more fully de-' scribed and claimed and s ownin the accompanying drawings, illustrating an excluplification of theinvention and 111 which Figure 1 is a longitudinal sectional view, artlyin elevation, of an irnprov'ed scale of this character constructed naccordance with the principles of this invention. Fig. 2 is a top planview of Fig. 1 with the platform or support andthe Vertical dialremoved. Fi 3 is an end elevation taken on line 3-3 0 Fig. 1. i

Referring more particularly to the drawlugs and in this exemphficationof the invention, the numeral 10 designates a sup- $pecification erthetters .Eatent.

porting base and projecting above the face of the base and preferably atone end thereof are spaced uprights or standards 11, 12. Journaled insuitable bearings in these uprlghts or standardsis a shaft 13, theentremities of which preferably project beyond therespective uprights orstandards and secured. to one extremity of the shaft 13 to rotatetherewith is a horizontally disposed. conical dial the base of which isdisposed. adjacent the upright or standard 12 and the apex thereof isdisposed toward the pl atforin or support i l. This dialis pref"- crablyinclosed withina casing or housing 15 which is provided with a suitableslot 16, through which the numbers on the dial.

may be exposed to the user. The other ex trernity of the shaft 13projects through a vertically arranged dial 17, and secured to theextremity of the shaft is a suitable indicator or pointer l8,j"whichrotates withthe shaft Band moves over the face of the dial 17 in a planeparallel with the plane of the dial.

Arranged between the uprights or standards 11, 1.2, is a weightedsegment 19 which is pivotally mounted by means of suitable knife edges20 engaging and resting in suitable bearings 21 respectively on theuprights or standards 11, l A suitable counterbalancing weight 223s alsoarranged between the uprights or standards ll, 12, and is operatlvelyconnected with the knife edges 20 for counter-balancing the weightedsegment 19.

The base 10 provided with an aperture or opening 23, which is locatedadjacent the conical dial and preferably disposed to one side thereofand arranged adjacent one side of the opening 23, and within the base isa leyer 24 which is su ported by suitable links 25 engaging suita leknife edges 26 at the extremitiesv of said lev'er,and the free ends ofthe links are adapted to en age suitable knife edges 27 secured to thease 10. The lever 24 is provided With an arm or beam 28, which extendsacross the opening 23 and within the base '10, the free end of whichterminates adjacent the supports 7 orstandards ll, 12. A similar lever'29 is pivotally supported' adjacent the other side of the opening. 23and parallel with the lever 24 by means of suitable links 30, oneextremity of which engages suitable'knife edges 31 on the lever 29 andthe free extremities thereof engage suitable knife edge bearings 32 onthe base and said links serve as a means for supporting one end of thelever 29. i

Projecting laterally from the lever 29 is an arm or extension 33, whichextends to a point adjacent the center of the openlng 23 and is providedwith a knife edge bearing 34 adjacent the free extremity thereof. A

similar knife edge bearing 35 is arranged on the .arm 28 of the lever 24and a suitable link 36 is arranged to engage the knife edges 34 and 35for pivotally connecting the arms 28 and 33 to form av compound lever.The platform or 'sup-' port 14 is provided with depending pro-' beamorlever 41, which is supported by knife edges 42 engaging and resting insuitable bearings 43 supported by the uprights or standards 11, 12. Thisbeam or lever 41 is preferably arranged transversely to the shaft 13 andis located at some. distance below the weighted segment 19 and isconnected to the segment preferably by means of an adjustable member 44having a flexible section 45 so thatwhen the end of the beam or lever 41is depressed, the member 44, together with the flexible section 45 willrock the segment 19 about its point of pivotal support. If desired, thebeam or lever 41 may be rovided with a receptacle 46 on the free endthereof adjacent its point of pivotal support, which is adapted toreceive a heavy object, such as shot or the like, for counter-balancingthe lever when desired. A suitable member 47 is pivotally connected byone end to the beam or lever 41 and is pivotally connected by its otherend to the extremity of the arm 28 and forms the operative connectionbetween the platform or support 14 and the beam orlever 41.- A suitablepinion wheel 48 is secured to the shaft 13 preferably intermediate theuprights or standards 11 and 12, and pivotally connected to the beam orlever 41 is a rack bar 49 which is adapted to engage the pinion wheel 48so that when the beam or lever 41 is moved about its point of pivotalsupport, the rack 49 will rotate the shaft 13 through the medium of thepinion wheel 48 and thereby rotate the conical dial within the casing 15and the indicator or pointer 18. The i'ack bar 49 may be held inengagement with the pinion wheel 48 in any desired or suitablemanner,,preferably by means of a weighted arm 50.

Secured toany suitable support, preferablythe uprights'or standards 11,12, is an arm or bracket 51, and pivotally supported thereby andintermediate the ends thereof is a tare beam 52, One extremity 53 ofthis beampreferably projects between the dials and is connected to thebeam 41 in any desired orsuitable manner, preferably by means of anadjustable member 54, one end of which is pivotally connected to theextremity 53 of the beam 52, and the other end is pivotally connected tothe beam or lever 41 adjacent the point of pivotal connection of theextremity of the member 47 therewith. The other extremity of the tarebeam 52 extends through a suitable aperture 55 in one wall of ablfurcated portion 56 of the bracket 51, which is located some distancebeyond the point of pivotal support of the beam: Located within thebifurcation 56 and adjustably mounted on the end of the beam 52 is asuitable counter-balancing weight or member 57, and slidably mountedupon the tare beam 52 is a pea 58 which may be held in its adjustedposition in any desired or suitable manner, preferably by means of ascrew 59.

g If desired, a suitable casing or covering 60, such as sheet metal orthe like, ma be arranged to close the space between the ials for thepurpose of protecting the parts of the scale, this eoverin beingprovided with a suitable aperture t rough which the extremity 53 of'thebeam 52 may pass.

If desired and in order to' take up the back lash or to relieve theparts of any sudden jar due to the placing of a weight upon the platformor support 14 or the removal thereof, a suitable'dash pot 61 may beprovided. This dash pot may be located in any convenient place,preferably at a point below the conical dial and adjacent'the 'ree endof the arm 28. This dash pot is preferably provided with a plunger rod62, the free extremity of which is secured to the arm 28 by means of asuitable connection 63.

With this improved construction of scale it will be noted that the dialis arranged in close proximity to the support or platform 14 and in sucha lows the user to stand close to the dial for reading the same but thedial is so located with re ation to the platform that it will not be ina osition to interfere with any obposition that it not only al-' jectwhic 1 may be placed upon the platform or support and at the same timethe object will not obstruct the dial. Furthermore, it will be notedthat with this improved con-' struction of scale, the compound leverconstruction permits the platform to be supported at a very lowelevation, thereby obviating the necessity of lifting a heavy obdetailsof the foregoing embodiment thereof,

have been thus specifically described, but

What I claim as new and desire to secure by Letters Patent is In a scaleof the class described, the com-p bination of a horizontal loadplatform, an upstanding support ofiset rearwardly and laterally withrespect to said platform, a

rotary conical dial mounted on said support above said platform with itsaxis horizontally disposed, and having its inclined surface above thenearest boundary substantially of said platform, and means actuated bysaid platform for rotating said dial.

In testimony whereof I have signed my name to this specification, in theresence of two subscribing witnesses, on thls first day of July A. D.1907.
